An NHS laboratory in Sheffield has admitted it failed to properly carry out blood tests on pregnant women.
More than 50 women had to be re-tested for sexually transmitted infections (STI) when infections were not picked up by the laboratory in Sheffield.
Six women from Sheffield were re-tested and a smaller number from Rotherham.
An investigation revealed the mistake after a pregnant woman tested positive for HIV at a clinic at Hallamshire Hospital in 2006.
